METHOD OF BURNING- :BRIcK.

Application filed February 28, 1927. Serial N0 ..171,453.

My present invention relates to the manufacture of brick, and more particularly to an improved method of manufacturing and burning soft mud brick.

In the manufacture of brick, and particu= larly in the burning of soft mud brick, it is customary to build the outside tiers of brick and the top courses of brick in a kiln out of regular way and this double amount ofcoal in the double tiers or layers materially helps to burn these outside brick. The adding of this additional coal is rather an expensive operation, particularly, since, whenever any of these double coal brick are placed by mistake in the inside of the kiln, they swell or lamie, and are destroyed, and in spite of all precautions, this happensquite frequently. v

In my present invention, I obviate the difiiculties above enumerated, and am enabled to dispense entirely with the use of double coal brick. The result is that but one kind of brick have to be manufactured, and in order to thoroughly burn the outside tiers of brick in the kiln, I utilize material "placed on the ledges of each unit of brick asthey are set down, which material becomes ignited as the heat of the burn increases and in this way a uniform brick is obtained.

The object of my invention, therefore, is an improved method of burning brick.

In the accompanying drawings illustrating a kiln constructed so as to carry out my invention, I V

Fig. l is an end view of a kiln, and I Fig. 2 is an enlarged sectional elevation nates a kiln shed provided with theusual and ordinary traveling crane 11- running on rails 12 extending longitudinally of the kiln and attached to the side walls thereof. 'At

tached also to the side walls and below the rails 12 are members 13, to which are attached books 14 serving asholding members for chains 15 attached to the top of portable scoving 16, such portable scoving fitting in the removable trough. 17 on the'fioorof the kiln. 18 designates units of brick construct- I ed in the usual manner and with the usual, amount of coal dust therein. The lower course rests on the floor of the kiln and it wlllbe noted that the second course of units 18 are offset or inset from the lower. course as clearly shown in Fig. 2, leaving-a ledge of relatively substantial width 19, on which I place. or pile coal dust 20. Each succeed- 111g course of units of brick 18 are arranged likewise, the ledge formed by the insetting of thesucceeding, course being filled with. coal dust 20, as above described. After the kiln is 'builtand'as illustrated in Fig. 1, a platting 21 is utilized to cover the top of the kiln, this platting being the ordinary platting or a portable platting such as shown and described in my copending application Serial No. 171,599, filedFebruary 28, 1927.

The kiln having beenfired in the usual way,

the burn is started and the interior units of brick 18 are entirely burned first. As the heat of the burn increases, theheaps of coal dust 20 on the ledges 19 become ignited and aid and assist in the burning of the outside layers or tiers of brick. The. coal dust 20 may be pure coal dust or may be coal dust mixed of any desired portion of slag, sand or other refractory material, and I find that under certaincircumstances, this is desirable as it retards the time of igniting the coal dust 20 and. also retards the burning thereof, rendering the resulting brick more uniform in character.

By properly proportioning the amount of coal 20 to the size of the kiln, which may be readily done by increasing or decreasing the width of the ledges 19 and by diluting the coal dust 20 with an adulterant as sand or brick in tiers, insetting said tiers of brick as the number of courses is increased to form a 5 ledge at each tler or course, P1301110 combustible material on the ledges thus librmed,

enclosing thekiln with scoving, whereby, as.

the heat of the burn increases, the layers of combustible material will be ignited and the outer tiers or courses of brick in the kiln uniformly burned.

In testimony whereof, I have signed my name to this specification. I
